A new song has gone viral on the Internet. The website hosting the song uses the function \large f\left(t\right)=200t^2 to represent the number of daily hits over time, where t is time in days. Use the function to predict the day on which the number of daily hits reaches 1,000,000. Show all work to receive credit for this question.

We want to find the value of t when f(t)=1000000. Substituting this into the equation and solving for t, we get:

1000000 = 200t^2

Dividing both sides by 200:

5000 = t^2

Taking the square root of both sides:

t = ±sqrt(5000)

Since time cannot be negative, we take the positive value:

t ≈ 70.71

Therefore, the number of daily hits will reach 1,000,000 on approximately the 71st day after the song went viral.
